• grab line shall be secured at four equidistant point around the circumference of buoy to form four equal loops.
• readily available on both sides of the ship, 1 in vicinity of stern.
• at least 1 on each side fitted with buoyant lifeline, length not less than twice the distance from stowage position to waterline or 30m whichever is greater.
• 50% lifebuoys should be fitted with self igniting lights.
• 2 lifebuoys with lights to have smokes and able to release from bridge.
• marked with ships name + port of registry in block roman letters.
Carriage requirement :
• passenger ship • cargo ship
under 60m = 8 under 100m = 8
60 - 120m = 12 100 - 150m = 10
120 - 180m = 18 150 - 200m = 12
180 - 240m = 24 200 & above = 14
240 & above = 36

• not ignite explosively or emit any flame during emission.
• not be swamped in seaway.
• continue to emit smoke, when submerged in water at least 10 sec.
• buoyant lifeline - min diameter 8mm, min breaking strength 5kn, non- kinking.
Life jacket
General requirements :
• shall not sustain burning or continue melting after being totally enveloped in fire for 2sec.
